What happened at 9/11 of course changed the scale of all this... It became an issue about fear, and our horror at looking, as I did, out of our windows onto the buildings that were burning. The horror we had in our hearts from this, allowed us... to give up basic freedoms. I’m not just talking about the ones the papers talk about all the time, our democratic and constitutional rights, but in the way we live, the way we block our streets.

I am a sculptor, my work is abstract and more often than not described as “post-minimalist.” Recently I was asked to contribute a work for a group showinHongKong. The curatorial frame of the show is “the ways objects produce space.” Rather than contribute a sculpture and hope for some sort of latter-day phenomenological experience between ‘object’ and ‘subject’ however, I suggested revisiting an urban design project that I had not worked on for over a decade. Eleven years ago I made a modest proposal to create a series of three massively flat and empty superblocks (two in New York and one in Washington DC). I last showed these proposals as three large architectural site models, just six months before September 11th attacks. Because my proposals seemed toforeshadowthe16 acregap left in Manhattan’s grid, I was urged to revisit the project. I didn’t, not because I didn’t feel I might have something to contribute, but because I was struck dumb horror. I refused to speak publicly about the project, and although the original show of models had been based on a long essay on the subject of art and public space, I stopped writing for years. Anyone familiar with myblogwill understand that this is not my usual MO. But looking back I am now very glad I shut up.

That is not to say I didn’t take interest in the site and the conversation around it. I followed the competition to choose an master plan, and still feel Sir Norman Foster’s unapologetically hard edged “kissing”chisels were the best of the lot. Most of what I saw and heard however, reinforced the observation that had inspired my proposals in the first place: the widespread inability to know the difference between what can and cannot be changed when it comes to architecture. By wide spread, I mean architects, politicians, critics and loudmouths at parties. Even after Modernist architecture’s fall from grace, the expectation is that big challenges must be addressed by massive projects, and that symbolic meaning trumps straight talk (observe Libeskind vs Foster).

While I sympathized with architect’s desire to respond to the attacks, I did not understand their responses. Architecture isn’t a symbol (that was the hideous confusion the attackers made), it is an expression; a concrete expression of an idea, an ethic, a desire. Modernists plazas are often characterized as “fascist” — the idea being that they are symbolic projections of power. Architects seldom, if ever, discuss lawns, park benches, or flower arrangements as expressions of power. Looked at as concrete ethical expressions, rather than symbols, we can begin to see these things for what they are: impediments, barriers, place holders, and dividers.

For the show in Hong Kong I ended up showing recreations of my three original counter-proposals, and a fourth proposal that has been gestating for almost a decade, but has suddenly taken on new relevance. I proposed building nine “Freedom Towers” arranged in a tight grid formation and completely occupying the available open space of Tiananmen Square.

A decade after I proposed paving flat large portions of New York and DC, I want to “occupy” Tiananmen Square with a formation of Freedom Towers. These may seem like two very different projects and two very different political contexts, but in fact they are the same. In 2001 I was suggesting that we had lost an important variety of public space and that our cities and our republic were lessened by that loss. That in the 40 years since the civil rights and ant-war protests of the 1960s American authorities have altered the landscape of our cities –— through changes in the rules that concerning public assembly (a process Naomi Wolf calls “overpermiticisation”), but also through bricks and mortar construction. Our public space has been “developed” out of existence.

In the wake of the massive protests in Wisconsin, the “Arab Spring,” and the Occupy movement in New York (and everywhere else), it feels important to once again raise the question of public space as a built environment. Rather than continue to argue that we build a new kind of space here, I am suggesting that we imagine what it would mean if we exported our current development schemes to other countries; to imagine them as the work of foreign regimes. What if the National WWII Memorial, with its heroic Speerian colonnade, sunken plaza, and ground-covering fountain, had been built in Tahrir Square rather than midway between the Lincoln Memorial and the Washington Monument? How would we feel if Russian authorities were to announce the construction of a large Frank Gehry designed Guggenheim be built over, Bolotnaya Square, the site of last December’s ballot-rigging protests in Moscow?

To mashup SOM’s Freedom Tower and China’s Tiananmen Square may, at first glance seem arbitrary, but it isn’t. Both New York’s Ground Zero and Beijing’s “Zero Point” are symbolically loaded sites. non-mainland Chinese associate Tiananmen with the 1989 pro-democracy protests, but for the Chinese it was already a site loaded with meaning when protesters chose that space to take their stand. In his book Remaking Beijing, the author Wu Hung describes the formation of Chinese end of this symbolic East-West axis....
